CVE-2026-73471: GStreamer gst-plugins-good out-of-bounds read in Nikon metadata parser

CVE-2026-73471 · Severity: medium · CVSS 6.1 · Published 2026-11-06

GStreamer is a multimedia framework that processes audio and video files. A flaw in the AVI file parser allows an attacker to craft a malicious AVI file that, when opened or previewed, causes the application to read memory outside its allocated buffer. This can result in application crashes or disclosure of sensitive information from memory.

Technologies: Gstreamer Gst-Plugins-Good. Vendors: Gstreamer.

Technical details

An unverified pointer dereference in the Nikon metadata tag parser within GStreamer's avidemux component allows out-of-bounds reads when processing crafted AVI files. The vulnerability is triggered automatically when playbin, decodebin, or gst-discoverer auto-plugs avidemux to handle media files, requiring only user interaction to open or preview the malicious file. Exploitation can cause crashes or limited memory disclosure; a fix is available in gst-plugins-good 1.28.6.

Affected products

  • GStreamer gst-plugins-good before 1.28.6
